The first trailer for Spencer, the Kristen Stewart-starring film about Britain's Diana, Princess of Wales and the end of her marriage to Prince Charles, has been released.

The drama from Jackie director Pablo Larraín is written by Peaky Blinders creator Steven Knight. Poldark star Jack Farthing portrays Prince Charles.

The royal couple's divorce was finalised in August 1996. Diana was killed in a car crash in Paris in August 1997.

Kristen Stewart has described the film as "a dive inside an emotional imagining of who Diana was at a pivotal turning point in her life"

The Spencer trailer synopsis reads: "The marriage of Princess Diana and Prince Charles has long since grown cold. Though rumours of affairs and a divorce abound, peace is ordained for the Christmas festivities at the Queen's Sandringham Estate.

"There's eating and drinking, shooting and hunting. Diana knows the game. But this year, things will be a whole lot different.

"Spencer is an imagining of what might have happened during those few fateful days."

Star Stewart has described the film as "a dive inside an emotional imagining of who Diana was at a pivotal turning point in her life".

"It is a physical assertion of the sum of her parts, which starts with her given name: Spencer," she continued. "It is a harrowing effort for her to return to herself, as Diana strives to hold onto what the name Spencer means to her."

The Impossible star Naomi Watts previously portrayed Diana in the 2013 biopic Diana. Emma Corrin recently starred as Diana in Netflix's The Crown. Elizabeth Debicki will take over the role for seasons five and six of The Crown.
